本文报道橡胶中龄芽接树高产综合技术开发试验的情况。三年的试验结果表明:(1)干胶产量增加30～40％,PR107和PB86年平均亩增产干胶28.5公斤,增加产值171元,扣除增加投资33.5元,获纯利137.5元。(2)平均干胶含量比对照区略高。(3)死皮增长率与对照区的差异不明显。
This article reports the rubber middle age budding tree high yield comprehensive technology development test situation. The results of three years showed that: (1) The dry glue production increased by 30 ~ 40%. The average annual growth rate of PR107 and PB86 was 28.5 kg, an increase of 171 yuan. After deducting an increase of 33.5 yuan, a net profit of 137.5 yuan was deducted. (2) average dry glue content slightly higher than the control area. (3) The difference between dead skin growth rate and control area is not obvious.
